Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello. Sounds to me like the timing went out. First see if the engine will run on starter fluid. If not check compression that will tell you a lot. Most likely the timing jumped or the fuel pump went out. Or you have a case of bad fuel. Hope this information helps. Lou
Ah never mind timing lol I was in auto pilot with test steps. Your issue is most likely fuel related. I would pull the fuel test port cap and drain some fuel into a glass mason jar and let it set for a hour and see if it separates. If it does you will notice a definite line of water and fuel. If not you will see the sediment floating in the fuel. If you just got gas I would suspect poor fuel quality. So I would stick with that until proved otherwise. Hope this information helps.
Lol yeah I don't blame you. Sorry for that. So p0171 is a fuel trim code. That's what you get when the fuel won't fire correctly. I still think it's s fuel issue until proved otherwise.
P2004 has to do with a adjustable intake runner. That would affect run ability but not starting.
Ok. Don't do the crank sensor yet. One step at a time. If you do too much at one time an something else happens then you. Will be chasing your tail figuring out if it was a failed new part or what. So just start with the fuel.
so it runs now with new gas?
OK, unplug the mass air flow sensor and see if it runs,
how many time did you try as it may not start right away
if the mass air flow sensor fails it will send the wrong air flow reading to the ecm and cause the wrong air fuel ratio,
ok, it should have started by then
see if there is one stocked at a local parts store plug it in and give it a try.
ah, ok i dont think i will be able to help unless you can get a scan tool that can read live data. if bringing the car to a shop is not a option for you let me know and i will opt out and see if another expert can assist.
no worries i will opt out, another expert should be along soon. so please do not reply back to me or it will lock the question back to me. if for some reason another expert does not assist you can follow the customer service links and get process your own refund. good luck please let me know what fixes it , take care.
